My invention relatesl to improvements in driers and to a method of drying.

. form a part of this specification wherein 'doors and its surrounding parts, Figure 5 is a detail perspecti An important object of my invention is the provision of a drier wherein various materials such -as bricks, tile or any product made from clays, shales', soils, or any product containing moisture may be successfully and l.

efficiently dried.- y 1 A `further object of my invention isto prov-ide a device of this character in which thevarious conditions existing in the drierv lmay becontrolled and adjusted at all tunes.

A further object of my invention is the provision of a device of the above men- 2 tioned character which will be of simple construction, easilyand economically operated, and highly eiicient in results.

Other objects of 'my invention will be apparent dunng the course of the following description. l

In' he accompanying drawings which like characters of reference denote like or corresponding parts throughout -the same,

Figurel is a top plan viewl of my improved drier, parts'bein removed,.

Figure2 isa longitu inal sectional view prising a base 11, side walls 12, end walls 13 and' top 14. The top and baseare preferably ormed rom concrete and the side walls of any suitable Amaterial such as'ooncrete,

bricks', or the like. The casing is divided into compartments by means of partitions running longitudinally thereof, said partitions Aeach comprising a central wall 15 and outer walls 16 spaced at each side from said center wall.

There are also' walls- 17 similar tocompartment walls 16 spaced from lthe casing side walls as shown. It willl be seen vthat chann- V bers..are provided between v the outer-walls 16 and central wall15,'and between walls 17 and 12. These chamber-'sare divlded cenf trally itt-18 s0 as to O-i'm'two longitudinally xtending chambers at each side of the chamers.

. The walls 16 series of Openings 18 communicating with the chambers, these openings allowing circulation of air. Y

An air duct 19 extends across the top of the casing at one end and communicates with the air chambers by means of passages'20, provided with valves 21. A fan 22, operated *and* 17 are formed with a j' by a motor23, connects with the air duct 19 and supplies air to the chambers, said supply of air being controlledby lthe valves A similar exhaust air duct 24 is varranged at the other end of the casing and is controlled in the same manner as the air duct 19. An exhaust fan 25 is connectedto this duct to exhaust the air from the chambers. A hot air furnace 26 connects with the fan 22 and is provided with a suitable air tem.

pering valve 27. A steamline '28 has branches 29 extending into the .air chambers, suitably controlled by valves, and sprays are arranged on the ends of the branches to y properly dii'use the moisture to huniidify the air in the chambers.

Each of the drylng .compartments is provided Awith a central, longitudinally extending gutter 30 which opens into transversely extending gutters 31 at either end of the casing. Driveshafts 32 are arranged in the gutters 31 and driven by motors 33.

Sprocket wheels 34 are arranged opposite.

the gutters 30. Drag chains 35 pa-ss over thesprocket wheels 34 and extend through the gutters 30. The lower length of the chains pass over idlers 36, and hooks 37 are arranged in spaced relation on'the -chain.- The drive shafts are controlled by any suit-.

able clutch mechanism operated by the levers 38, and the hooks 37 are adapted to en gage suitable cars '39 upon which the materialfto bedried is placed. i

The ends 'of the compartments are closed by doors 40, preferably of steel which are raised and.lowered'by means of the sheaves 41, worm and spur gear 42 and cable 43, thecable passing over pulle'ys 44 arranged as' shown in Figure 4. vThe doors are notched at their lower-ends to allow lthe drag chains and hooks to pass.

are -preferably formed-10i? brick. A brick The walls 16 and 17 of.the;compartments suitable for this purpose is shown in Figures 5 and 6. This-brick has its'endstapered to acentral point 45 spaced a slight distance ,from the end of the brick, the tapered walls not extending the full height of the brick but spaced from the bottom thereof so as to v leave a flange 46 which projectsa slight disthat an opening 18 is formed between them,

said opening tapering from Vboth sides to the middle. These bricks may be arranged one row above the other so as to present a staggered series of openings on each layer of bricks, as shown in Figure 5 or rows of plain bricks 47 may be interposed between the rows of pointed bricks in order t0 space the rows of openings, as shown in Figure 6.

In operation', the cars are brought into the compartments, and the doors tightly closed.

Air is admitted to the chambers at one endl and exhausted at" the other. The air is preferably sent into one of the chambers at each side of the compartment, for instance the top, and exhausted at the other chamber, the bottom, or it might be taken in on the top on one side and on the bottom on the other side, or it might be taken in on all of one side and exhausted on the other. This is controlled by the valves 21 and may be changed during the drying operation. The steam may be admitted at any desired time and to any desired extent.

It will be seen that I have provided a device which'will insure perfect distribution of air and control over the conditions existing in the drier.

While I have shown and described the preferred embodiment of my invention, it is to be understood that various changes in the size shape andarrangement oparts may be resorted 'to without departing from the spirit of my invention or the scope of the Subjoined claims.
